I'm trying to determine which of the 3 Kisae charger zones is connected to the house batteries. I'm going to swap out the 2 house batteries for a couple of AGM batteries and my understanding is that I need to re-configure the house battery zone for the different battery type (AGM vs flooded).

I just checked the kisae web site and it seems that it can charge different battery chemistries simultaneously.

"KISAE's Abso line of smart battery chargers offers fully automatic, multi-stage battery charging, plus the ability to charge three (3) separate battery banks. The ultimate set-and-forget charger, these products incorporate special charging algorithms designed to quickly and accurately recharge and maximize the life of AGM, Gel, Flooded or Lithium batteries. These chargers will also charge multiple battery chemistries simultaneously."
